7. I think all the numbers are written in standard form
The length of line BE on the given line segment is 3.5 m.
The given parameters:
- <em>Length BD = 3 m</em>
- <em>Length CD = 15 m</em>
- <em>Length AB = 21 m</em>
<em />
The sketch of the given line segments is presented in the diagram uploaded.
The length of BE is determined by applying similar triangle theorem as follows;
![\frac{CB}{AB} = \frac{BD}{EB} \\\\\frac{15 + 3}{21} = \frac{3}{EB} \\\\18EB = 63 \\\\EB = \frac{63}{18} \\\\EB = 3.5 \ m](https://tex.z-dn.net/?f=%5Cfrac%7BCB%7D%7BAB%7D%20%3D%20%5Cfrac%7BBD%7D%7BEB%7D%20%5C%5C%5C%5C%5Cfrac%7B15%20%2B%203%7D%7B21%7D%20%3D%20%5Cfrac%7B3%7D%7BEB%7D%20%5C%5C%5C%5C18EB%20%3D%2063%20%5C%5C%5C%5CEB%20%3D%20%5Cfrac%7B63%7D%7B18%7D%20%5C%5C%5C%5CEB%20%3D%203.5%20%5C%20m)
Thus, the length of line BE on the given line segment is 3.5 m.
